Thermal infrared remote sensing and soil gas radon for detecting blind geothermal area

Advances in Thermal Infrared Remote Sensing Technology for Geothermal Resource Detection

“…To eliminate spurious anomalies induced by non-geothermal resource factors such as topography, urban heat island effects, and vegetation coverage, various scholars have proposed distinct methods [53,57,58]. Among these strategies, mitigating the impact of terrain is particularly paramount.…”

“…Generally, areas with higher soil radon concentrations correspond to elevated surface temperatures, which serve as a valuable indicator for assessing the shallow geothermal energy potential. Sun et al (2022) successfully employed soil radon concentration data along with LST inversion derived from TIR remote sensing data of the Landsat-8 satellite to guide the drilling of geothermal wells in the Tangjiashan area, Sichuan Province, China [58]. Moreover, hydrochemical analysis is a commonly used method in geothermal exploration.…”
